  • I'm sure there'll be a growing number of people asking this question with Google Image charts being deprecated...I'm searching high and low for a solution myself. The options I've looked at so far are pretty terrible. #1 draw charts directly somehow by hand in OL (out of poly's?); #2 use Google Charts print function to export an image from the <canvas> tag, which is hacky as hell and doesn't even support IE9.

  • I would go for ExtJS (N.B. i am not evangelist of that)

Well, took me a couple of hours but I found one way to do it.

It requires you to use dojo.js, (which unfortunately I can't use for my project but thought I'd share for anybody else that's looking).

Basically, as I understand it, dojo adds a custom wrapper to openlayers map which allows you to add Dojo GFX Shapes and Widgets - which includes Pie Charts!

See a good demo here: http://acuriousanimal.com/2012/01/23/dojo-openlayers-new-challenges
